Screening and shearing mechanism and ration feeding assembly

Abstract

This invention relates to a sieve-shearing mechanism and a quantitative feeding component. It aims to solve the technical problems of quantitative control and clumping of bird feed during artificial feeding of wild animals. The quantitative feeding component includes a feed storage bin, a pushing mechanism, and a positioning feeding mechanism. The pushing mechanism uses a motor-driven auger column to stir and push the bird feed in the storage bin, preventing clumping. The positioning feeding mechanism, driven by the pushing mechanism, precisely controls the amount of bird feed discharged each time. The sieve-shearing mechanism is located between the pushing mechanism and the positioning mechanism, and includes a relatively movable section, a spherical coupling, a circular valve plate, and upper and lower shearing blades. The shearing action of the blades cuts large clumps of feed before discharge, preventing blockage. During operation, the motor-driven pushing mechanism stirs and transports the bird feed, while the positioning mechanism precisely discharges it. During the stirring and pushing process, large clumps of feed are cut by the sieve-shearing mechanism, achieving smooth discharge and precise quantitative control while preventing blockage.

Description

Technical Field

[0001] This invention relates to a field quantitative feeding device, and more particularly to a quantitative feeding component and its screen-cutting mechanism that can accurately and quantitatively supplement food for wild animals and has anti-clogging function.

[0002] This quantitative feeding device can be installed and used near forest animal protection stations or endangered animal habitats to automatically and quantitatively supplement the food of various wild animals, helping wild animal populations to successfully overcome periods of food scarcity caused by climate or human activities and maintain regional ecological balance. Background Technology

[0003] With societal development, the habitats and food sources of wild animals have been damaged and affected to varying degrees, leading to significant survival pressures during seasons of food scarcity. Artificial feeding has become an effective conservation measure to help wild animals survive these seasons.

[0004] Current methods of manual feeding mostly involve simply scattering bird feed randomly, which cannot achieve quantitative feeding and easily leads to resource waste. Bird feed stored for a long time is also prone to clumping, and direct feeding will clog the equipment. Some equipment uses a spiral conveyor system, which cannot effectively cut large clumps of feed; some equipment uses scrapers for cutting, but the structure is complex and the cutting effect is not good.

[0005] Therefore, how to accurately quantify the feeding of wild animals and effectively chop up clumps to prevent blockages has always been a pressing technical problem in this field. In existing technologies, such as the Chinese patent announcement CN109997728B, a control method, device, and mobile terminal for a bird feeder are disclosed. This method acquires video information of the birds through a camera installed on the bird feeder and determines whether water, bird feed, or paper rolls need to be added based on the video, thereby achieving remote intelligent control of the bird feeder. However, this method is mainly aimed at poultry feeding and does not consider the issues of quantitative food control and chopping up clumps. Overall, existing technologies have not yet shown a design solution that effectively addresses the dual needs of quantitative feeding of wild animals and chopping up clumps.

[0006] This invention, by improving the transmission structure and setting up a positioning mechanism and a screen-cutting mechanism, can not only achieve precise quantitative feeding of bird feed, but also effectively cut off large clumps of feed generated during storage, basically solving the problems of anti-clogging and precise quantitative feeding in the prior art. Summary of the Invention

[0007] In view of this, the present invention provides a quantitative feeding component, which prevents bird feed from clumping through a stirring mechanism and precisely controls the feeding amount through a positioning mechanism. Combined with a screen-shearing mechanism to cut large clumps of feed, it realizes precise quantitative supplementation of food for wild animals, which is conducive to maintaining ecological balance.

[0008] The technical solution of this invention is implemented as follows: a quantitative feeding component, comprising: a grain storage bin, a pushing mechanism, and a positioning feeding mechanism;

[0009] The grain storage silo is an openable structure, and its interior space is used to store bird feed.

[0010] The pushing mechanism is installed inside the grain storage bin and is used to stir and push the bird feed inside the bin.

[0011] The positioning and feeding mechanism is connected to the pushing mechanism, and the amount of bird feed discharged each time is precisely controlled based on the flow of bird feed driven by the pushing mechanism.

[0013] The auger column is rotatably mounted inside the grain storage silo; one end of the central shaft is fixedly connected to the output shaft of the drive motor; the first gear is fixedly mounted on the central shaft; the second gear is fixedly connected to one end of the auger column and meshes with the first gear. This preferred embodiment further defines the specific structure of the pushing mechanism, which is beneficial for implementation and understanding.

[0014] Preferably, the positioning and feeding mechanism includes a material stop, a material barrier, a U-shaped frame, a connecting shaft, a third gear, and a cam;

By relating the positional relationship of the shearing mechanism to the aforementioned device, its functional position within the overall system is clarified.

[0020] Preferably, the sieve shearing mechanism also includes a top bead, which is fixed to one of the blades of the lower shearing blade and can move up and down to abut against the annular valve plate. The top bead, through its movement, drives the valve plate to move, thus shearing and chopping large pieces of bird feed.

[0021] Preferably, the upper shearing blade is fixedly connected to the lower end of the central shaft of the auger column. This clarifies the relative fixing method of the upper and lower shearing blades.

[0022] Preferably, the lower shearing blades are arranged in a circular pattern. The circular blade arrangement increases the cutting area.

Detailed Implementation

[0041] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0042] It is important to note that terms such as "first," "second," "symmetric," and "array" are used only to distinguish between descriptive and positional descriptions and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified with terms such as "first" or "symmetric" may explicitly or implicitly include one or more of that feature; similarly, when the quantity of certain features is not limited by words such as "two" or "three," it should be noted that such features also explicitly or implicitly include one or more features.

[0043] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0044] Example 1: As Figure 1-6 As shown, this embodiment of the invention provides a quantitative feeding component, which, when placed in the wild to feed birds, can effectively help wild animals survive cold or dry seasons when food is scarce, thus maintaining ecological balance. It includes a food storage bin 1 and an actuating component. The food storage bin 1 is an openable and sealable structure with internal space for storing bird feed. The actuating component, installed inside the food storage bin 1, mainly includes a pushing mechanism 2 and a positioning feeding mechanism 3. The pushing mechanism 2 is used to stir and push the bird feed in the food storage bin 1, driving the bird feed to circulate through mechanical force, preventing the bird feed from clumping and clogging due to prolonged stagnation. The positioning feeding mechanism 3, based on the flow of bird feed driven by the pushing mechanism 2, uses the coordinated movement of its structure to precisely control the amount of bird feed discharged each time.

[0045] The positioning and feeding mechanism 3 uses the power output from the pushing mechanism 2 to precisely control the amount of bird feed discharged through motion transmission. Specifically, the actuator in the positioning and feeding mechanism 3 is connected to the second power output part in the pushing mechanism 2. The rotational force generated by the pushing mechanism 2 during operation is transmitted to the actuator of the positioning and feeding mechanism 3, causing it to move according to a set program to control the amount of bird feed discharged, thus achieving precise definition of the amount of bird feed discharged each time.

[0046] In one embodiment, the pushing mechanism 2 includes an auger column 201, a central shaft 202, two first gears 203, a second gear 204, and a drive motor 205. The two ends of the auger column 201 are rotatably connected to the inner wall of the grain storage silo 1 via mounting brackets and bearings to achieve rotation of the auger column. The drive motor 205 is installed outside the grain storage silo 1, and its output shaft is fixedly connected to one end of the central shaft 202, which transmits the torque of the drive motor 205. The two first gears 203 are respectively fixedly embedded on the outer wall of the central shaft 202. The second gear 204 is fixedly connected to one end of the auger column 201, and the outer ring of the second gear 204 meshes with the outer ring of one of the first gears 203 to achieve power transmission.

[0047] The output shaft of the drive motor 205 drives the central shaft 202 to rotate. The rotating central shaft 202 uses two first gears 203 to drive the second gear 204 to rotate. The rotating second gear 204 drives the auger column 201 to stir and push the bird feed in the grain storage bin 1.

[0048] In one embodiment, the positioning and feeding mechanism 3 includes two baffles 301, several baffles 302, two U-shaped frames 303, a connecting shaft 304, a third gear 305, two cams 306, four piston rods 307, four sleeves 308 and four springs 309.

[0049] The outer walls of the two baffles 301 are slidably connected to the bottom of the outer wall of the grain storage silo 1. Several baffles 302 are fixedly connected to the bottom of the inner wall of the grain storage silo 1. Two U-shaped frames 303 are respectively fixedly connected to one side of the two baffles 301. The connecting shaft 304 is rotatably connected to one side of the outer wall of the grain storage silo 1 through a bearing. The third gear 305 is fixedly connected to one end of the connecting shaft 304. The outer wall of the third gear 305 meshes with the outer wall of another first gear 203. Two convex... All wheels 306 are fixedly connected to the bottom of the outer side wall of the connecting shaft 304. The outer side walls of the two cams 306 are slidably connected to the inner side walls of the two U-shaped frames 303 respectively. All four sleeves 308 are fixedly connected to the outside of the grain storage bin 1. The four piston rods 307 are slidably connected to the inner side walls of the four sleeves 308 respectively. One end of the four piston rods 307 is fixedly connected to one side of the two baffles 301 respectively. The four springs 309 are fixedly connected between the four piston rods 307 and the four sleeves 308 respectively.

[0050] The third gear 305 drives the two cams 306 to rotate via the connecting shaft 304. The rotating cams 306 use the two U-shaped frames 303 to make the two baffle frames 301 move in opposite directions, so that the two baffle frames 301 can alternately overlap and misalign with the baffle grid 302, so as to quantitatively control the discharged bird feed.

[0051] When the drive motor 205 is started, its output shaft drives the central shaft 202 to rotate. The rotating central shaft 202, through two first gears 203, drives the second gear 204 and the third gear 305 to rotate. The rotating second gear 204 drives the auger column 201 to stir and push the bird feed in the grain storage bin 1, preventing the bird feed from caking and being unable to be discharged. The rotating third gear 305, through the connecting shaft 304, drives two cams 306 to rotate. The rotating cams 306, through two U-shaped brackets 303, cause two baffles 301 to move in opposite directions. One of the moving baffles 301 coincides with the baffle grid 302 and drives the piston rod 30. 7. The spring 309 is compressed, and another baffle 301, using the compressed spring 309 and piston rod 307, slides into the grain storage bin 1 and forms a misalignment with the baffle 302 to seal the bottom of the grain storage bin 1. This allows the bird feed in the grain storage bin 1 to be metered between the two baffles 301. Then, the cam 306, which continues to rotate, uses the U-shaped frame 303 to make the two baffles 301 move in opposite directions again, so that the two baffles 301 can alternately overlap and misalign with the baffle 302, so that the metered bird feed can be discharged from the grain storage bin 1. During the discharge process, the bird feed in the grain storage bin 1 can be prevented from entering between the two baffles 301.

[0052] Among the various types of bird feed, there are ordinary basic pelleted bird feed, various fortified bird feeds, and herbal bird feeds with added medications. During long-term storage, some of these bird feeds may clump together to varying degrees. To prevent large clumps of bird feed from falling directly into the positioning feeding mechanism 3 and causing blockage, a screen-blocking and shearing mechanism 4 is installed. Its structure includes:

[0053] 1. Movable section 41: It is installed between the lower part of the auger column 201 and the upper part of the baffle 302 inside the grain storage bin 1. Its shape is an inverted cone and it can rotate relative to the grain storage bin 1;

[0054] 2. Spherical coupling part 42: disposed at the central shaft end extending downward from the auger column 201;

[0055] 3. Circular valve plate 43: It is fitted in a ring around the outer circumference of the spherical coupling part 42, with a certain gap between it and the side wall of the movable section 41;

[0056] 4. Lower shear blade 44: Fixedly installed in the movable section 41, the blades are arranged in a circle, and the central part is sleeved on the auger column 201;

[0057] 5. Upper shearing blade 45: Located above the lower shearing blade 44, and centrally fixed to the lower end of the auger column 201;

[0058] 6. Top bead 46: Fixed on one of the blades of the lower shearing blade 44, and can be adjusted up and down to slide until it contacts the valve plate 43;

[0059] 7. Transmission gear 47: Fixed on connecting shaft 304;

[0060] 8. Meshing teeth 48: are located on the outer circumferential surface of the movable section 41 and are in transmission engagement with the transmission gear 47.

[0061] When the screen shearing mechanism 4 is working, the top ball 46 first pushes the valve plate 43 to one side, thus opening the gap between the other side of the valve plate 43 and the moving section 41. After the gap is opened, the bird feed in the grain storage bin 1 immediately flows down from this gap into the space above the baffle 302 until the space is filled with bird feed.

[0062] The space filled with bird feed ensures continuous feeding by the positioning and feeding mechanism 3. Then, the drive motor 205 starts, and the auger column 201 of the pushing mechanism 2 drives the movable section 41 to rotate, with the two rotating in opposite directions. During the rotation, bird feed of different positions and sizes arrives sequentially below the valve plate 43.

[0063] Small, unclumped bird food flows smoothly through the gap between the valve plate 43 and the wall of the movable section 41; large, clumped bird food is flipped, squeezed, and crushed by the rotating valve plate 43, and simultaneously cut into pieces by the rotating double blades 44 and 45; the chopped pieces of bird food then flow through the gap.

[0064] In this way, bird feed of different positions and sizes can flow smoothly under the valve plate 43 and be discharged through the baffle 302, effectively preventing blockage.

[0065] Example 2: A quantitative feeding component, whose structure is basically similar to that of Example 1, with the main improvement being:

[0066] The drive motor 205 was replaced with two synchronously operating servo motors. The two motors drive two independent pushing mechanisms 2, which makes the bird feed in the grain storage bin 1 more thoroughly and evenly mixed.

[0067] In the positioning and feeding mechanism 3, the connecting shaft 304 is changed to a spline connection structure, making the transmission of the third gear 305 more stable;

[0068] The screen shearing mechanism 4 is equipped with two sets of upper and lower shearing blades 44 and 45. The two sets of blades are fixed in a staggered manner, which increases the cutting area and improves the cutting efficiency.

[0069] This embodiment further improves the working efficiency and stability of the quantitative feeding component by improving the motor transmission method, optimizing the transmission structure, and increasing the cutting area.

[0070] Example 3: A quantitative feeding component, whose overall structure is similar to that of Example 1. The main improvement is:

[0071] The bottom of the grain storage silo 1 is equipped with a lifting platform, and a quantitative feeding component is installed on the lifting platform; the lifting platform is driven to move up and down by a linear lifting mechanism.

[0072] During operation, the lifting platform is first raised, and the pushing mechanism 2 and positioning mechanism 3 start working. After the set amount of bird feed is discharged, it switches to the lowering state. During the lowering process, the lifting platform will carry the quantitative bird feed that has been fed out of the grain storage bin 1 in the opposite direction.

[0073] This structural improvement enhances material feeding efficiency.

[0074] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
